Summary:

Summary Tape File 4 consists of three sets of
computer-readable data files containing highly detailed tabulations of
the nation's population and housing characteristics produced from the
1980 Census. The files contain sample data inflated to represent the
total United States population. The files also contain 100-percent
counts and unweighted sample counts of persons and housing units. This
series is comprised of STF 4A, STF 4B, and STF 4C. All three series
have identical tables and format. Population items tabulated for each
area include demographic data and information on schooling, ethnicity,
labor force status, children, and details about occupation and
income. Housing items include data on size and condition of the
housing unit as well as information on value, age, water, sewage and
heating, vehicles, and monthly owner costs.

United States Department of Commerce. Bureau of the Census. Census of Population and Housing, 1980 [United States]: Summary Tape File 4B Extract. ICPSR08229-v2. Ann Arbor, MI: Inter-university Consortium for Political and Social Research [distributor], 1999. https://doi.org/10.3886/ICPSR08229.v2

All geographical entities from the complete STF 4B
series are included in the extract file for each state, along with the
seven major record types out of a possible total of 39. The record
types in the extract file each represent a population group for which
the detailed tabulations were presented. Included are record types for (1) total population, (2) Whites, (3) Blacks, (4) American Indians, Eskimos, and Aleuts, (5) Asians and pacific Islanders, (6) "other races", and (7) Spanish origin. The geographic entities for which all
STF4 data items are tabulated and reported for the above groups in
this extract are: states (along with numerous rural, urban, and SMSA
components of each state), SCSAs (standard consolidated statistical
areas), SMSAs (standard metropolitan statistical areas), urbanized
areas, all counties and county equivalents (along with rural and
rural-farm components of counties), MCDs/CCDs (minor civil
divisions/census county divisions), places of 2,500+ population, and
American Indian reservations/Alaskan Native villages (and county
components of American Indian reservations). Each logical record in
these files is comprised of 86,064 characters. For each record there
are 44 record segments (physical records) of 1,956 characters each.
These numbers represent the amount of data in a geographical area for
each record type. Thus the total amount of data available for a given
geographical area may be seven times as high as these numbers, if all
the record types are present for that area. The number of data records
varies by state.

Methodology

Sample:
These files include, for most variables, sample data from
the 1980 Census inflated to represent the entire population of the
United States. Some data from "100-percent counts" and unweighted
sample counts are also provided.
